Very beautiful object granite, very good. The object is well thought out, with a polishing the entire surface except the end of the pestle and the mortar. This will crush the seeds correctly, dry bread, etc. It's also more effective to scrub the food between two rough surfaces rather than typing them. So no noise, no exhaustion to lift the pestle. Indeed, it is rather heavy. Ultimately very satisfied with this choice, because the quality is by appointment and not to scratch my table where I put it, I pasted below skates for chairs.
